Happy World Statistics Day!My latest: "World Statistics Day has joined the exclusive list of 126 U.N.-designated International Days celebrated this year, suggesting that today is more important than at least three-fifths of all other days."

My latest: Political betting markets suggest that Greece's prime minister, Alexis Tsipras, may have misread the mood of his own electorate, and there's a two-in-three chance that the "yes" case will win the referendum.
